Question about 2000 Audi A4
I had a VW Rabbit in which rain leaked onto the fuse box, which caused many things to turn on at once. The alternator kept trying to start the engine while driving in the rain. They replaced the alternator nine times. The headlights came on in the middle of the night when it rained - I was in bed and the car keys were on the nightstand.
Check your fuse box. Is it rusty or wet?

Sounds like you've got a short-to-ground and turning the parking light switch on is activating the ground circuit for boght the horn and wipers. solution may be as simple as a replacing the switch assembly (though the process to do that could be toilsome, depending on the make & model) or it could require an intensive diagnostic of the circuitry to find the short. could also be a relay (don't think that all three items would share a single one, though).
one quick test would be to check for a shared fuse for all three items, which would support the hypothesis that it's a ground short. if they don't all share a common fuse, pull the fuse for the parking lights and see if turning the switch still causes the issue. if it does, it's most definitely a shorted ground (as the fuse should be on the positive side of the circuit). if it doesn't occur when the fuse is pulled, maybe you're actually leaking voltage to the other two accessories - unlikely, but i supose it's possible.
